the belief that one is best suited to accomplish a task
The instinct for survival is paramount under normal circumstances. Still, even animals throw themselves into danger to help a human friend. The drive that overcomes Self-Interest is Responsibility. Responsibility exists when one cares more for others than for oneself. The problem occurs when a character believes he knows what is best for someone and that someone doesn't agree. "It's for your own good," and "This is going to hurt me more than you" are two expressions that exemplify this attitude. Sometimes the character is right in believing he knows best, other times not. But either way, Responsibility can cause problems when it is imposed on another rather than offered to them. Responsibility can both be given or taken.
syn. assumed propriety, believed appropriateness, self designated aptness, accepted suitability
